What do buildings look like through Earth's glasses? by Earth's Perspective
Post billboards that show a building behind them through a "reality" lens, through the "Earth's glasses." Place ads in major polluted cities
Create campaign similar to that of Truth anti-smoking. Post billboards in front of giant buildings in major cities that emit high amount of greenhouse gases.
Billboards will show the building(s) located behind them through a "reality" lens, through the "Earth's glasses." The building on the billboard will look very unhealthy, and will be smoking a cigarette, emitting gases and smoke. Underneath billboards, text will say something like "Just because we can't see it, doesn't mean it's not there."
Set up billboards in various big cities, online at different major media outlets.
"You wouldn't appreciate it if your guests did this in your home, would you?"
Overall---compare green house gas emissions to visible smoke we can see. It needs to be relatable to the general public and something everyone can grasp.
